VACUUM- CLEANER.

Specification of Letters Patent;

Application filed June 15, 1909. eria1 No. 502,203.

To all whom it may concern:

Be it known that I, WILLIAM H. KELLER, a citizen of the United States, residing in the city and county of Philadelphia, State of, Pennsylvania, have invented a new and useful VacummCleaner, of which the following is'a specifipat-ion.

My present.invention relates to the well known vacuum cleaners which are now in extensive use for cleaning purposes and consists of a novel construction, of a vacuum cleaner, wherein means are provided for enabling the same to be driven either by a suitable -motor of any desired or conventional type or the same may be driven by manually actuated means and for this purpose I have shown in the drawings a hand wheel, which is adapted to be manually operated.

My invention further consists of a novel construction of a vacuum cleaner, wherein a rotary pump is preferably employed which communicates with a vacuum or filtering compartment, a lnotgr being removably mounted on the frainewbrk or base of the device and opcratively connected with the rotatable pump, nieans being also provided for manually driving the pump.

" a It further consists of'other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying dra wings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalitics as herein shown and described.

Figure 1 represents a sectional elevation of a vacuum cleaner embodying my invention. Fig. 2 represents a plan view thereof. Fig. 3 represents a side elevation of the rotary pump, one side thereof having been removed in order to more clearly illustrate.

the construction thereof. Fig. 4 represents a sectlonal view of the rotary pump. Fig. 5 represents. a side elevation of the motor and a standard therefor, which may be'employe'd in case the manually actuated driving means are dis ensed with.

Siini ar numerals of reference indicate corresponding parts in the figures.'

Referring to the drawings :-1 designates the base of the machine. which is sup orted in any suitable manner and if desired may be provided with suitable rollers.

' 2 designates an air tight casing supported on the base 1 in any suitable manner and the sides of thiscasing preferably consist of a plurality of layers or thicknesses of material. The upper end of the layers of the casing is closed by a collar 3, the side of which is suitably gr'ooved as is indicated at 4,

the top of t e casing 2, it being seen from Fig. 1 that a'suitable packing strip 5 is employed whereby an air tight oint is formed between the collar 3 and the casing 2. The upper surface of the collar 3 is suitably thereby adapltin the same to be seated upon 8 designates a dustba ring, the upper end of which is provide with a laterally grooved as'indicated at 6 thereby adap tiplg' Patented Aug. 1, 1911.

extending flange 9 adapted to be seated on r the packing strip 7 when the parts are assembled position. v 1

1O designates a cover which is provided with the laterally extending flanges 11 which are suitably grooved in order to receive apacking strip 12 whereby an air tight joint is formed between the flanges 12 and the flange 9 on the dust ring 8. The cover 10 is preferably formed with a dependingflange 13 which is seated within the dustbag ring ,8.

14 designates the air inlet which is adapted to be connected with a suitable hose, to which the suction or blowing nozzle is attached, said inlet leading to a'chamber 15 formed within the boss or enlargement 16 of the cover of the casing and communicating through the port- 17 with the vacuum or! 'journaled therein at 45 a hand wheel 46 laden air entering filteringeompartment 18, as will be readily understood by reference to Fig. 1.

In order that the conditionof the dustthe machine may be readily seen-by the operator, I preferably close the upper end of the chamber-15 by means of atransparent plate 18 which is secured in position by any suitable means such as, for example, the Washer 19 and fastening devices 20', suitable packing strips 21 being preferably employed in order to form an airtight joint at such parts,

22 designates the outlet port leading from "the vacuum compartment 18 and communieating with the inlet port23 of the pump casing 24 which latteris mounted on or secured to the base 1 in any desired manner. The pump casing 24 is preferably provided with a removab e cover 25 whereby the operating pa'rts of the pump are rendered readily accessible. In the present instance,

for purposes of illustration, 1 have shown the type of pump employed as consisting of a rotary pump comprising the'cas'ing 24 in which is mounted a drum 26' one. shaft-27.

.other desired point '28 designates a bearing pinor rod GCCQIlr trically carried by the drum 26 and-provided with a plurality of blades 29 which are adapted to slide within the slotted rollers or bearings 30' mounted in the seats 31 of the drum 26." .The blades 29 rotate within ,the compartment 32 so that the air is drawn through the inlet 23 and is dis charged through the exhaust port 33 which communicates with the atmosphere or any of utilization and which is adapted to be connected with a suitable hose whereby my device may be employed for blowing when desired.

The shaft 27of the rotor has mounted thereon a plurality of pulleys 34 and 35.

\Thebase 1 is provided with .ajournal or bearing 36 iii which is mounted a standard 37 on which is adjustably secured a set col lar 38. I

39 designates a bracket mounted on the standard 37 above ably secured to said standard in the present instance. it being seen that: th e brael et 39 is provided with a split collar 40 through which passes the bolt 41 whereby the bracket 39 is suitably secured with respect to the standard'37.

42 designates a motor of any desired or conventional type although in practice I ,prefer to employ an electric motor which the collar 38 and remov-' ed on the standard 37, said bracket having which is provided with a suitable actuated handle 47.

4.8 designates a handle loosely mounted on the bearing 45-or secured to the bracket- 44: in any suitable manner so that the operator may glrifil. oncend of the handle 48 while rotating the hand wheel 46, which latter is provided with a suitable groove theresingle standard such wheel or thebrackct 39, carrying the motor may be removed as desired according to, the conditions arising in practice.

The cover 10 is preferably provided with slotted extensions I 52, through which the rods 53, carried by to'pass, said rods being provided with smr able thumb nuts 54 whereby the rover K? may be readily removed when desired.

vacuum cleaner will now be readily apparcnt and is as follows:lVhen it is desired 56 is passed around the pulley 43 and around the pulley 34. Upon the rotation of the motor, air will be drawn into the umping chamber 32 and the dust-laden air will 10, thence into the chamber 1 5 andthen'ce through the port 17 into the vacuum chamlocated the dust bag 55 Whichlatter is secured to the dust ring 8 in any desired manner. The-air which has now been freed from its impurities passes through the inlet'port 22, the inlet chamber 32 and thence to the exhaust port 33 and to the atmosphereor other desired point of utilization. In case it is. desired to manually actuate from the pulley 34 and the belt 49 will. be
